The silll is further provided? witE an? inner' s'illl channel`l bottom 'walll 472,` an upstandingfint'erfy mediate; lip 48 formed by al foldi of,4 the@ sill; menibe'r,anr

outer sill channel bottom wall 49, and a folded leg portion 50 adapted to abut the weather stop side members 28 and the permanent sill 21 of the window opening.

Opposed jamb members 34 are channel-shaped, as

shown in Figs. 3, 4, 9 and l0. Each of said members is bent to form an inner leg 52 folded upon itself and spaced from a second leg 60, folded upon itself as at 62, by a jamb member bottom wall S. Each jamb member is further bent to form an extension 66 of leg 62, which extension is folded upon itself, as shown, and is co-extensive with the height of the jamb members, and is adapted to form an exterior wall for the sash guide channels hereinafter described. Y Inner and outer upper sash guide channels are formed cooperatively with said jamb members 34 in the follow-V ing manner. An inner wall 54 is telescopically received within the upper half of the frame within the folded leg 52. Said wall is folded upon itself at its free edge 56 to form a bearing surface for a sash slidably mounted in the upper inner sash guide channel. l

An intermediate wall 64, ,generallyv Z-shaped in cross section, having a leg portion 68 telescopically received within folded leg 62 of the jamb members, is mounted in the upper half of the frame between exterior wall 66 and inner wall 54. A body portion 70 spaces leg 68 from folded leg 72 and approaches the jamb member bottom wall at an acute angle. This inclination of body portion 70 of the'intermediate wall provides a yieldable spring tensioned bearing surface for a sash mounted in the upper outer Vsash guide channel, tending to hold said sash in selected raised positions.

The lower half of each jamb member 34, as shown in Fig. l0, is provided with a generally L-shaped sash gripping strip 74 having one leg 76 telescopically received within folded leg 52 of the jamb member and the other leg overlying the bottom wall 58 of the jamb member. Said second mentioned leg of the sash gripping strip is bent toward bottom wall v58 as at 78 yieldably spacing the strip from said bottom wall and adapted to hold a sash mounted in the lower half of the frame in selected raised positions. Sash gripping strip 74 and bottom wall S8 of the jamb members are perforated as at 80 and 82 for reasons hereinafter set forth. y

, The lower and upper sashes of the assembly indicated as A and YB. respectively in the iigures may be formed either of wood or metal construction and overlap at their meeting rails, as shown in Fig. 5f They are of a vertical dimension such that sash B may be raised in the upper outer sash guide channel a distance suicient to allow sash A to be raised to permit its bottom rail 83 to pass inwardly over lip 48 of the sill member. Sash A is provided on the interior side of each side rail with a sash catch, as shown in Figs. 2 and 6. This sash catch is formed by a generally L -shaped arm 84 pivotally mounted on hinge pin 86 fastened to the side rail 88 of the sash. The catch is adapted to be swung to move the free end of arm 84 selectively into perforations S0 and 82 heretofore described.

To install the window assembly frame within the permanent window opening, the trim panel, double hung sashes, and the window stop are removed and replaced by the frame. The trim panel is then replaced and secured to the sill, header and jamb members of the permanent window opening, thereby holding the Vsaid window assembly frame between the weather stop and the trim panel without any other fastening means.

The sashes are successively mounted. in the frame through the lower half of the frame. They may be mounted, as shown in Figs 5 and ll, by slidable movement. Sash A may be locked in the position shown in Fig. 5 by swinging arm 84 from the dotted position, shown in Fig. 6, to the lock position wherein the arm is inserted in perforation 82 of the jamb members.` With the lower sash so locked the upper sash cannot be lowered. Lip

` combination, a header member, a sill member, opposed' complementary jamb members, said sill member eXhibit` 48 of the frame sill member serves to prevent inward movement of the bottom rail 83 of the sash.y Y

Fig. 7 shows the sashes mounted to permit air to pass over the upper sash and yet prevent any unauthorized person from entering the room from outside the building. With the sashes in the position shown in Fig. 5, to arrange the sashes as shown in Fig. 7, sash A is moved within the frame so that its bottom rail rests between lip 36 and inner wall 46 of the sill. sash may be inclined` so that its top rail passes under the lower edge of inner wall 54 of the upper inner guide channel. Without completely removing the sash from the frame the sash is then slightly elevated and positioned so that the bottom rail is seated on bottom wall 49 of the sill. The upper meeting rail 85 of sash A is then moved toward the frame until lip 86 engages the lower edge of the upper inner sash guide channel wall 54.

The'sash catches are swung 'so that the arms 84'enter`,l perforations in the jamb members. Sash A is then Sash B is lowered until 'its meeting rail rests against the exterior faces of the side rails'of:

locked in position.

sash A, all` as shown in Fig. 7.

To perform the above described operations of inserting the sashes within the frame, or positioning them therein so that the lower sash is inclined' inwardly of the frame with itsmeeting rail overlapping' the lower ends of the inner wall 54, it will be noted that the dimension betweenV the bottom wall 49 of the sill member andthe lower end of Vthe inner wall 54, is less thanthat of the vertical dimension of the lower sash from vthe top of its lip 86 to the under face of its bottom rail 83. It will be further noted that the dimension 'from bottom wall 47 to the lower end of inner wall 54 is greater than the above described vertical dimension of the lower sash.l

Three general positions of the sashes within the frame are therefore evident from the drawings and description, namely; where both sashes are in the closed position, as shown in Fig. 5; where the upper sash is completely elevated and the lower sash partially elevated, as shown in Fig. 11; where the lower sash is tilted inwardly of the window opening and the upper sash lowered to rest against the exterior faces of the side rails of said lower' sash.
